Intro To Understanding Ultrasound Physics Exam With Complete Solution 50. What is the range of periods commonly found in waves produced by ultrasound systems? A. 0.001 to 1s B. 0.06 to 0.5 us C. 0.2 to 1 ms D. 10 to 100 ns - CORRECT ANSWER-B. Ultrasonic imaging waves have a period in ps. The period is the range of 0.06 to 0.5 the time of a single cycle. Period is the loolto reciprocal of frequency. A wave with a frequency of 2 MHz has a period of 0.5 usec. A wave with a frequency...

Fundamentals of Physics Exam 4 | Questions and Answers Sonar is a technology used to make maps of the sea floor, as well as to find fish and military targets. Sonar is very similar to medical ultrasound, in that it makes images using sound, but the sonar device is attached to the bottom of a boat and projects downward through the water. While medical ultrasound uses frequencies in the MHz, sonar works best with lower frequencies, because it has to travel longer distances. Calculate the wavele...
